Verdict

The call

The clearest difference is rating: Muro Box at 5.0 against NS MIDI Player's 4.5. Muro Box also leads on update cadence (every 9 days vs every 3 months) and iOS requirement (15.0 vs 17.5). NS MIDI Player's advantage is ratings volume (211 vs 5) and review sentiment (84% vs 71%). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Muro Box holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: NS MIDI Player has 211 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 71% of Muro Box's written reviews are positive against 84% of NS MIDI Player's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Muro Box ships an update every 9 days, NS MIDI Player every 3 months. The most recent releases landed on November 2, 2026 and November 7, 2026 respectively.
